We don't know; it's never really made clear. I like to think Eru put different creatures out of the reach of his Elves, so that they would discover that they didn't know everything (which, I believe, is a problem with those Elves...), and, once they did, to trust Eru's plan, which the Valar did not...the summoning to Aman, anyone?
I sincerly doubt that Melkor could fashion his own creature, Valar though he was. I don't think he was that creative.
Or perhaps I'm wrong, and Melkor just looked at a snake and thought; hey, if I give that wings, and legs, fire-breath, and spellcasting eyes, it'll be my minion!
But this I doubt; the dragon sickness (guarding a wealth that has no use) convinces me that they were already there, and he just took advantage of them.
